2 Effective separating length the introduction of column packing 

Test mixture benzene-carbon tetrachloride charge 300 ml 40 mol% carbon tetrachloride 

Device for the random introduction of small packing units (Allenby and L Heureux) 

These results demonstrate the following facts, which so far have been given little attention in laboratory work. 

The HETP, at a constant load, is dependent on the effective column length.
